Phoenix Contact 1768781 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1768781 is a 4-position terminal block plug with female sockets, 0.197" (5.00mm) pitch, and 225° free-hanging wire entry configuration. This component is classified as Active product status and is designed for screw-based cage clamp termination in industrial control and power distribution applications. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and connector geometry align with the original specification, enabling direct replacement in applications where wire entry angle and mounting orientation permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1768781 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed UL specifications (15 A, 300 V minimum)
• Mechanical Geometry: 4-position configuration with 0.197" (5.00mm) pitch and M3 screw termination
• Connector Type: Female socket plug with screw-based cage clamp termination
• Wire Compatibility: Support for 12-30 AWG (0.2-2.5mm²) wire gauge range
• Mounting Configuration: Free-hanging (in-line) orientation
• Regulatory Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The TE Connectivity AMP Connectors 796640-4 qualifies as a substitute based on matching electrical ratings, identical pitch and position count, equivalent termination method, and compatible wire gauge specifications. The primary operational difference is wire entry angle (180° versus 225°), which affects installation geometry but does not impact electrical or mechanical function when space constraints permit straight-angle wire routing.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1768781 is the primary specification when 225° wire entry angle is required for the application layout. This part maintains Active product status with full ROHS3 compliance and UL94 V-0 flammability certification.

TE Connectivity 796640-4 serves as a functional substitute when 180° straight-angle wire entry is acceptable or preferred for the installation geometry. This part also maintains Active product status with equivalent ROHS3 compliance and UL94 V-0 certification. The wider wire gauge range (0.05-3mm²) provides additional flexibility for conductor sizing. Selection between these parts should be based solely on wire entry angle requirements and available installation space, as all electrical and mechanical parameters are equivalent.

Both parts are suitable for direct replacement in applications where the specified wire entry angle accommodates the connector orientation. No performance degradation occurs when substituting between these parts within their respective installation constraints.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796640-4 directly replace Phoenix Contact 1768781 in all applications?

A: Direct replacement is possible when the 180° wire entry angle of the TE Connectivity part is compatible with the installation space. If the application specifically requires 225° wire entry geometry, the Phoenix Contact part must be used. All electrical ratings, current capacity, voltage specifications, and termination methods are equivalent.

Q: Are the screw torque specifications the same between these parts?

A: No. Phoenix Contact 1768781 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) torque, while TE Connectivity 796640-4 specifies 0.79 Nm (7.0 Lb-In). Verify the correct torque value for the part being installed to ensure proper cage clamp engagement and wire retention.

Q: What is the difference in wire gauge compatibility?

A: Phoenix Contact 1768781 supports 12-30 AWG (0.2-2.5mm²). TE Connectivity 796640-4 supports 12-30 AWG (0.05-3mm²). The TE Connectivity part accommodates a wider range of conductor cross-sections, including finer gauges below 0.2mm² and larger conductors up to 3mm².

Q: Are both parts ROHS3 compliant?

A: Yes. Both Phoenix Contact 1768781 and TE Connectivity 796640-4 are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting equivalent regulatory requirements for industrial applications.

Q: What is the wire strip length requirement for each part?

A: Phoenix Contact 1768781 requires 7mm wire strip length. TE Connectivity 796640-4 requires 6-7.5mm wire strip length. Ensure proper conductor preparation according to the specific part being installed.

Q: Can these parts be stacked or used in multi-level configurations?

A: Both parts are single-level connectors (1 level, 4 positions per level). TE Connectivity 796640-4 includes side stacking capability as an additional feature. Verify application requirements before selecting based on stacking needs.
